Phillips and straight screw driver slips out. Drag link socket too thick. There must be a specific tool for this.
That looks like the one on my Hyundai. Put a short length of flat stock in a pair of vise grips. I just used a big screw driver. It should not be that tight. It is just plastic.![]()

Try a quarter.

I can tell you from mine, it is a lot bigger that the widest part of a #2 phillips head but it might be worth a shot.I am thinking, if you can find a Philip screwdriver with the shank made like a cross, I would cut off the tip. Now you have the proper screwdriver. This is my opinion as I have the screwdriver but have not tried it as I don't need it. When I encounter this problem this will be my go to solution.
I don't think it is usually stuck that badly. I think the cross thread is just to give you two places to put a big flat blade screw driver. Mine was accessed through a hole in a cross brace.It's deep into the radiator tank, quarter wont fit.
Sure, I can cobble together something but the head is almost gone even for that. It IS tight. Plus to loosen it out you have to press in hard so as not to strip out the head. Can't believe there isn't a specific tool made for this.

#3 phillips screwdriver should do the trick.
I guess I don't enjoy a scalding shower of antifreeze as much as you do.
I rarely open radiator drains anymore and many newer vehicles don't even have them anymore.
Remove the lower hose, and stop wasting time.
Time is money.
I'd rather have a drain pan under the plug and have the hot coolant come out cleanly than pull a hose that is often in a difficult to access location and hot coolant all over my arms and shirt with half of it spilling on the ground.

I'm not sure why folks are mentioning hot coolant. We never messed with stuff like that on hot engines. I'm not going to burn myself for a customer nor did I expect my techs to do that..

Reminds me of plastic plugs on pumps and sprayer parts, you try various screwdrivers and then end up using a Vise-grip to remove them.
Snap-on and other company's make 1/4" to 1/2" drive screwdriver bit sockets that would fit that slotted size.
Regarding Strouty's response, has anyone drained coolant in a shop and not got some on the floor?
What's that one on the left called? My computer screws are like that.
